I'm finally back in Japan and tomorrow is my first day of work! Hooray!
Anyway, on to my question. I was wondering earlier, how I could say, "another one." Of course, I know I could say something along the lines of 「他の飲み物」, but I also know that if the item is known, that it can be left out: 「青いセーターを買いました。赤いのも買いました。」(just an example...I know that it would be easier to just combine those into a single sentence). But 他 seems to be a noun / の-adjective. So if I wanted to say "buy another one" and leave out the item due to context, would I say 「他のを買う」, 「他ののを買う」, or is there another way to express this?
よろしくお願いします。
